Hair clipper blade set with transport element

Abstract

A hair clipper with a blade set, includes at least one stationary or one adjustable cutting comb and one shearing blade driven in oscillation in the transverse direction essentially parallel to the front edge of the cutting comb. The hair clipper may have a hair transport element, which has a transport toothing, which is arranged essentially along the cutting edge of the shearing blade at a distance from the cutting edge of the shearing blade. The shearing blade is arranged between the cutting comb and the hair transport element. The cutting edge of the shearing blade extends beyond the front edge of the hair transport element.

What is claimed is: 
     
       1. A blade set of a hair clipper, comprising:
 a stationary cutting comb; 
 a shearing blade driven in oscillation in a transverse direction essentially parallel to a front edge of the cutting comb; and 
 a hair transport element arranged to transport hair, the hair transport element having a transport toothing with teeth that are arranged adjacent to one another and are arranged essentially along a cutting edge of the shearing blade at a distance from the cutting edge of the shearing blade, wherein the shearing blade is arranged between the cutting comb and the hair transport element and wherein the cutting edge of the shearing blade extends beyond a front edge of the hair transport element, and wherein the hair transport element has a substantially plate-like form aligned in a co-planar fashion with the shearing blade. 
 
     
     
       2. A blade set according to  claim 1 , wherein the transport toothing has an essentially sawtooth profile and wherein sawteeth of the sawtooth profile each have a steep flank and a flat flank. 
     
     
       3. A blade set according to  claim 1 , wherein the transport toothing of the hair transport element is arranged on the hair transport element running essentially along an entire portion of the cutting edge of the shearing blade. 
     
     
       4. A blade set according to  claim 1 , wherein the front edge of the hair transport element is essentially parallel to the cutting edge of the shearing blade. 
     
     
       5. A blade set according to  claim 1 , wherein tips of the teeth of the transport toothing are arranged relative to each other so that the tips define a first section of an envelope curve which forms a convex boundary of the transport toothing. 
     
     
       6. A blade set according to  claim 1 , wherein the hair transport element is firmly joined to the shearing blade, over a surface thereof. 
     
     
       7. A blade set according to  claim 1 , wherein the hair transport element is driven in oscillation via a driver with the shearing blade. 
     
     
       8. A blade set according to  claim 1 , wherein the transport toothing has a first section and a second section, and steep flanks of sawteeth of the first section of the transport toothing and steep flanks of the sawteeth of the second section of the transport toothing point in essentially opposite directions to each other. 
     
     
       9. A blade set according  claim 8 , wherein the first section of the transport toothing is arranged in mirror symmetry to the second section of the transport toothing. 
     
     
       10. A blade set according to  claim 1 , wherein the transport toothing has a middle tooth at a center with two steep flanks. 
     
     
       11. A blade set according to  claim 1 , wherein a distance between the front edge of the cutting comb and the cutting edge of the shearing blade is adjustable while a relative position of the cutting edge of the shearing blade to the front edge of the hair transport element remains constant when a distance between the front edge of the cutting comb and the cutting edge of the shearing blade is changed. 
     
     
       12. A blade set according to  claim 11 , wherein the distance between a front edge of the cutting comb and the cutting edge of the shearing blade is adjustable with an activating element. 
     
     
       13. A hair clipper, comprising:
 a stationary cutting comb; 
 a shearing blade driven in oscillation in the transverse direction essentially parallel to the front edge of the cutting comb; 
 a hair transport element arranged to transport hair, the hair transport element having a transport toothing with teeth which are arranged adjacent to one another and are arranged essentially along a cutting edge of the shearing blade at a distance from the cutting edge of the shearing blade, wherein the shearing blade is arranged between the cutting comb and the hair transport element, wherein the cutting edge of the shearing blade extends beyond a front edge of the hair transport element, and wherein the hair transport element has a substantially plate-like form aligned in a co-planar fashion with the shearing blade; 
 a housing, which encloses an electric motor for driving the shearing blade in oscillation; and 
 a driver, coupled to the electric motor and the shearing blade to drive the shearing blade in oscillation in response to the electric motor being turned on, wherein the hair transport element is one of: coupled firmly to the shearing blade or coupled to the shearing blade in such a way that the hair transport element moves along with the shearing blade when the shearing blade is driven in oscillation. 
 
     
     
       14. A hair clipper according to  claim 13 , further comprising:
 a hair transport element having an engagement to receive the driver. 
 
     
     
       15. The blade set according to  claim 1 , wherein the transport element is arranged to transport hair in the transverse direction. 
     
     
       16. The blade set according to  claim 1 , wherein the transport element is arranged to eject hair away from the hair clipper. 
     
     
       17. The blade set according to  claim 1 , wherein the teeth of the transport toothing are arranged along an entire length of the cutting edge of the shearing blade. 
     
     
       18. The blade set according to  claim 1 , wherein the transport toothing includes at least 5 teeth. 
     
     
       19. The blade set according to  claim 2 , wherein, for each of the sawteeth, each end of each flat flank terminates at an end of a steep flank. 
     
     
       20. A blade set of a hair clipper, comprising:
